I never heard of this film or of the filmaker in the documentary. I saw the title on Netflix and watched it one day after work. The documentary itself was good. The subject matter was interesting. It was no murder mystery. The mystery is why did it happen. The mystery is what heppened to this man and why did the wife go into the rabbit hole with him. I never understand murder suicides and to kill your child, and wife then yourself is unrelateable to me. Especially writing in your wifes blood. Like I said it was a good dicumentary.
